<P>PROBLEM TO BE SOLVED: To provide a game machine including random number generation means for generating an appropriate random number value even when the generation of a hardware random number stops. <P>SOLUTION: The random number generation means includes: a first random number generating part A including a counter 1101 for performing counting repeatedly at a predetermined time interval and a counter latch 1102 for acquiring the value of the counter at a predetermined trigger; a second random number generating part V including a refresh register 1111 used to refresh a dynamic RAM, a random number value register 1113 in which the value is updated at a predetermined time interval, a delay circuit 1114 holding the random number value generated last time, and a second synthesis part 1115 for synthesizing the outputs of the refresh register 1111, the random number value register 1113, the delay circuit 1114; and a first synthesis part 1121 for synthesizing the outputs of the latch counter 1102 in the first random number generating part A and the second synthesis part 1115 in the second random number generating part V. <P>COPYRIGHT: (C)2012,JPO&INPIT |
